The 80 Tooth GT2 Timing Pulley is a large GT2 belt motion component used in Voron 2.4 style builds, DIY 3D printers, CNC machines, robotics, automation projects, belt reduction systems, and custom mechanical assemblies. Designed for compatible GT2 timing belts, this pulley provides synchronized belt movement for printer motion systems and other compact machine builds where smooth, repeatable travel matters.
This pulley features an 80 tooth GT2 profile, 5mm bore, and black anodized aluminum body. The larger 80 tooth design is useful in belt-driven systems where pulley diameter, belt wrap, motion ratio, or mechanical layout are important. It is especially relevant for Voron 2.4 inspired printer projects, DIY CoreXY machines, custom gantry systems, and motion assemblies that use GT2 belt hardware.
GT2 timing belts are widely used in 3D printers and light-duty motion systems because they provide accurate belt-driven movement in a compact format. This 80 Tooth GT2 Timing Pulley is designed for compatible GT2 belt systems and works well in layouts that use 6mm wide GT2 belts. Always confirm belt width, tooth profile, bore size, and pulley spacing before installation.
Voron 2.4 style machines and other high-performance DIY 3D printers often rely on precise GT2 belt routing for smooth and repeatable motion. This pulley can be used in printer builds, rebuilds, upgrades, belt reduction systems, and custom motion layouts where an 80 tooth GT2 pulley with a 5mm bore is required. Always confirm your specific printer revision, bill of materials, and motion design before ordering replacement hardware.
The black anodized aluminum body provides a clean, professional appearance while keeping weight low. Aluminum pulleys are commonly used in printer and machine builds because they offer a strong balance of stiffness, low mass, and durability. The black finish pairs well with aluminum extrusion frames, black hardware, and clean custom machine layouts.
The 5mm bore makes this pulley suitable for compatible 5mm shafts, motor shafts, axles, shoulder screws, or custom mounting hardware depending on your design. Before installation, confirm that the pulley fits the shaft correctly and that any set screws, spacers, washers, or collars are installed with proper clearance. A pulley that is misaligned or loose can cause belt tracking issues, noise, uneven wear, and poor motion accuracy.
Although this pulley is especially useful for Voron 2.4 and DIY 3D printer builds, it can also be used in CNC projects, robotics mechanisms, laser engraver upgrades, plotters, camera sliders, automation projects, and prototype machines. Any GT2 belt-driven system that requires an 80 tooth pulley with a 5mm bore may benefit from this part.

Before installing the 80 Tooth GT2 Timing Pulley, confirm that your belt is a compatible GT2 timing belt and that your shaft, motor shaft, or axle hardware matches the 5mm bore. Mismatched parts can cause wobble, slipping, binding, poor belt tracking, or premature wear.
Proper pulley alignment is important for smooth and accurate motion. The pulley should sit square to the belt path so the belt tracks evenly across the teeth. Misalignment can cause belt edge wear, noise, skipped motion, uneven tension, or rubbing against nearby parts.
If your pulley uses set screws, tighten them against the proper shaft surface or flat where applicable. Use moderate torque and avoid stripping the set screw or damaging the shaft. For high-vibration printer and CNC applications, removable threadlocker may be used if compatible with your build.
Make sure spacers, washers, collars, brackets, and printed parts do not rub against the rotating pulley or belt. The pulley should spin freely after installation with no side binding, shaft wobble, or interference.
Use reasonable belt tension for your machine design. A belt that is too loose can skip or produce inaccurate motion, while a belt that is too tight can increase bearing load, create noise, wear the belt, or strain motor shafts and brackets.
Keep the pulley teeth and belt path free from dust, chips, filament debris, grease buildup, and abrasive particles. Contamination can reduce belt life and create rough or noisy motion. Inspect the pulley during regular printer or machine maintenance.
To keep the black anodized finish clean, avoid abrasive tools, harsh cleaners, and unnecessary scratching during installation. Wipe with a soft cloth before final assembly if the pulley will be visible on the finished machine.
